Description
Technical field
The present invention relates to the pyrolysis art of carbonaceous material, it is a kind of Electromagnetically inducing biomass pyrolyzing and liquefying reactor, be specially adapted to the pyrolysis of biomass such as fuel wood, agricultural crop straw, waterplant, also applicable to solid-fuelled pyrolysis such as coal, resinous shale and municipal wastess.
Background technology
Biomass energy is one of human use's energy the earliest, has wide, renewable, the low cost and other advantages of distribution.Biomass account for 15% in global Energy Consumption, are only second to coal, oil and natural gas.
To be sun power be stored in a kind of form of energy in the biology with the chemical energy form to biomass energy, it derives from photosynthesis of plants directly or indirectly, and in various renewable energy sources, biomass are unique, it is the sun power of storing, a kind of especially unique reproducible carbon source.Biomass are widely distributed occurring in nature, and in China's plant husbandry prosperity, annual photosynthesis produces the available biomass energy and amounts to 5.12 hundred million tons of standard coals.These raw material major parts are directly burnt, and do not have fine utilization, and transformation efficiency is only about 10%.If be liquid bio matter oil with Wood Adhesives from Biomass then will have improved the quality of utilizing of biomass energy greatly, also improved energy density simultaneously, and easily stored transportation.
Biomass pyrolysis liquefaction is biomass are degraded to product liquid and a part of gaseous product and solid product after being heated under the situation of complete anoxic or limited oxygen supply a process.
Biomass pyrolysis liquefaction be middle temperature (500～650 ℃), high heating rate (104～105 ℃/s) and the utmost point lose heart under the condition of the body residence time (less than 2s), with the direct pyrolysis of biomass, product is through cooling fast, can make the condensation before further fracture generates gas of middle liquid product molecule, thereby obtain the biomass liquid oils of high yield.The bio oil that the biomass pyrolysis liquefaction reaction produces can be made oil fuel and industrial chemicals by further separation and extraction; Gas is looked the height of its calorific value, can mix as industry or domestic gas separately or with other high heat value gas; Biomass charcoal can be used as promoting agent etc.
The biomass pyrolysis liquefaction system generally comprises raw material crushing and drying plant, feeding unit, liquefying reactor (pyrolysis producer), gas-solid separating device, quickly cooling device and gas transportation facilities etc., wherein, liquefying reactor is the core, and its operation scheme has determined the kind of liquefaction technology.At present, the fast pyrolysis legal system is equipped with the liquefying reactor that bio-oil adopts and mainly contains two big classes: a class is for there being carrier gas, be commonly referred to: fluidized bed reactor, be characterized in that drag force that biological particles and thermal barrier mainly rely on gas motion and produced collides and mix, to realize the exchange of momentum and heat, as fluidized bed type, circulating fluid bed type and spouted fluidized bed formula; Another kind of is no carrier gas, be commonly referred to: un-fluidized-bed formula reactor, be characterized in that biological particles and heating carrier mainly rely on the displacement movement of self to collide and mix, to realize the exchange of momentum and heat, as rotation conical, vacuum moving-bed type.
The advantage of fluidized bed reactor does not mainly contain moving parts, and structure is comparatively simple, and working reliability is big, and operation life is long etc.; But shortcoming is to need the introducing of fluidizing agent and keep a certain amount of solid thermal carriers in fluidized-bed.Fluidizing agent is generally the part of pyrogenous origin gas or high-temperature flue gas, and solid thermal carriers are generally sand.The introducing of fluidizing agent has improved system's operation energy consumption on the one hand, because this part adds the technological process that gas also will experience heating and cooling; On the other hand, the introducing of fluidizing agent can be diluted the not condensable gases that pyrolysis produces, and its calorific value is greatly reduced, and uses to run into certain difficulty.Owing to require a certain amount of hot sand, and in bed, to keep fluidized state in the fluidized-bed, so to the serious wear in the bed as solid thermal carriers.
Un-fluidized-bed formula reactor is just in time opposite with fluidized bed reactor, advantage is seldom or not to need to add gas, the energy consumption and the pyrolysis cost of system have been reduced, avoided the dilution of inflammable gas, but shortcoming is a reactor contains moving parts, requires quite high to material with thermotolerance bearing, wear resistance, stopping property etc.The rotation conical reactor, it is bored with one heart by inside and outside two and forms jointly, and inner cone is motionless, and outer cone pivots.The inner rotary awl must be rotated by the overhanging support of a spiral arm, and the bearing that supports outrigger shaft must be worked under high temperature and high dust operating mode for a long time, difficulty is quite big, in addition, the rotation conical reactor also needs inert heat carriers such as sand, and sand will ceaselessly be done geneva motion between two awl walls, and it is also quite serious to the wearing and tearing of high-temperature wall surface, therefore, the rotation conical reactor exists deficiencies such as complex structure, cost height, work-ing life be short.
The vacuum moving bed reactor is to adopt molten salt mixture to heat biomass to realize pyrolytic, and the heating of molten salt mixture needs pyrogenous origin not condensable gases additional combustion chamber burning liberated heat again.And not only frictional wear is more serious owing to adopt moving-bed, and sealing is also comparatively difficult.
Summary of the invention
